The short answer
A screenplay is a written blueprint for film, television, or streaming content. It follows specific industry formatting conventions and relies almost entirely on action and dialogue to convey story, because everything eventually happens on screen. Feature screenplays typically run 90 to 120 pages (one page equals roughly one minute of screen time). Structure and format matter as much as content, because screenplays are read by professionals who expect specific conventions.
Screenwriting is a distinct creative discipline with specific technical conventions and specific story demands. Below is the working introduction: what a screenplay actually is, the format rules that matter, and how the craft differs from other fiction writing.
What a screenplay actually is
A blueprint for a filmed production. Unlike a novel, which is the finished work in itself, a screenplay is an intermediate document that directors, producers, and actors read to build the eventual film. This changes the craft significantly: screenplays cannot rely on interiority (only what appears on screen can be included), and they follow specific formatting conventions that non-industry readers often find strange.
The core format conventions
Slug lines mark each new scene (INT. KITCHEN NIGHT). Action lines describe what happens on screen in present tense. Character names appear in capitals when speaking. Dialogue sits under the character name. Parentheticals below the character name give brief acting or delivery cues. Standard font is 12pt Courier or similar monospace. One page approximately equals one minute of screen time. Deviating from these conventions marks the writer as unfamiliar with the industry.
Feature length versus television
Feature films typically run 90 to 120 pages. Half-hour television runs 22-30 pages. Hour-long television runs 45-60 pages. Streaming has loosened these conventions somewhat, but industry readers still expect adherence unless the format deliberately signals otherwise. Length signals format signals expected structure.
Structure in screenwriting
Three-act structure dominates in features. Act one runs roughly 25% of the script. Act two runs 50%. Act three runs 25%. Specific structural beats have specific expected page numbers (the inciting incident by page 12, the midpoint at page 55-60, the low point around page 75, the climax around page 90-100). Some structures deviate deliberately, but the deviations are deliberate rather than accidental.
A screenplay is not a novel with dialogue tags. It is a specific technical document with specific conventions. Learning the format is not decoration; it is the price of admission to the industry.
The show-don't-tell rule intensified
Novels can access interiority directly. Screenplays cannot. If a character is angry, the screenplay must show something specific the audience can see or hear that implies the anger. Internal monologue does not appear on screen. This constraint forces screenwriters to think entirely in visual and audible terms, which is one of the specific craft challenges of the form.
Dialogue in screenwriting
Screenplay dialogue works differently from novel dialogue. Every line has to serve the specific purpose of the scene. Subtext matters even more because there is less internal thought to fall back on. Dialogue that would work in a novel often sounds stilted on screen. Reading screenplays aloud reveals problems the page cannot.
Common screenwriting mistakes
Novel-style prose in action lines instead of the specific compressed style screenplays require. Dialogue that carries backstory characters would not actually speak. Too many characters, so no single character develops enough. Missing structural beats or arriving at them at the wrong page numbers. Formatting deviations that signal unfamiliarity with the industry.
How to learn screenwriting
Read professional screenplays widely. Many are freely available online. Read the film first, then the screenplay, then watch the film again. This reveals what appears on screen versus what was on the page. Take a specific screenwriting book (Robert McKee's Story or Blake Snyder's Save the Cat are common starting points) and apply its framework to one full script. Write short scripts before attempting features.
Where screenplays meet an audience
Traditional screenwriting audiences are producers, studios, and eventually theatrical or streaming viewers. Independent and web series creators increasingly reach audiences directly. On community based platforms, where reach is earned through voted, deliberate audience backing, independent scripted content finds the specific audiences that traditional distribution may overlook. Cracy is built for this shape, so screenplay-based creators can find the audience their work fits.
